description The invention discloses a preparation method of a nitrogen-doped porous carbon material for SO2 gas adsorption, and the preparation method comprises the following steps: S1, rapidly pouring hot water into a mixed solution containing lotus root starch, zinc salt, 2-methylimidazole, ethylenediamine and water to form hydrogel, and carrying out vacuum drying to obtain an MOF-coated lotus root starch composite material; the temperature of the hot water is greater than or equal to 80 DEG C; and S2, calcining the MOF and lotus root starch composite material in the step S1 in an inactive atmosphere to obtain the nitrogen-doped porous carbon material for SO2 gas adsorption. According to the present invention, the rapid formation of the hydrogel ensures the uniform compounding of the MOFs and the lotus root starch, the grinding link does not exist in the process, the non-grinding mixing ensures that the prepared carbon material can maintain the special morphology of the MOFs material, and the existence of the adopted r
